Description
Uni-T UT18C Voltage and Continuity Tester
The Uni-T UT18C is an advanced voltage and continuity tester designed for quick and convenient diagnostics of electrical installations under various operating conditions. The device enables AC/DC voltage measurement, continuity testing, three-phase voltage and phase sequence testing, as well as detection of positive and negative polarity. Thanks to the backlit LCD display and LED indicators, the user can quickly read the result and efficiently assess the condition of the installation.
Wide measurement range and precise readings
The UT18C model displays voltage at levels of 12 V, 24 V, 50 V, 120 V, 230 V, 400 V, and 690 V, and the LCD display allows for reading voltage in the range of 6–690 V and frequency from 40 Hz to 400 Hz. The measurement accuracy for voltage on the LCD is ±(1.5%+5), and for frequency ±(3%+5), which facilitates more precise parameter control than with LED indicators alone. The tester also detects overvoltage in the range of 713–788 V, enhancing safety during operation.
Extensive functions for installation and service work
The UT18C is equipped with a phase rotation test in the range of 57–400 Vac for three-phase installations at 50–400 Hz, single-wire L2 voltage detection in the range of 100–690 V, and a continuity test for resistances from 0 Ω to 100 kΩ with audible and LED signaling. It also features an RCD test for 230 V operating voltage at 50–400 Hz and a self-test function that checks all LEDs and the LCD display. A major advantage of the device is the ability to perform tests without power in the 100–690 V range, which enhances its usefulness in emergency situations.
Practical design for everyday use
The tester meets the IP65 standard and is classified as CAT IV 600 V, making it well-suited for use in demanding environments. The device offers a silent mode, an automatic standby function with a current draw below 10 μA, a built-in flashlight, and a low-battery indicator at approximately 2.5 V. Powered by two R03 batteries, weighing 280 g, and measuring 272 × 85 × 31 mm, the tester is a convenient and versatile tool for electricians.
